SPINDLE-BODY BoL'r'faNnfMoUNfrme rnnnnron* Application filed April 16, 1923. y Serial No. 632,504.

To all whom it may conce-rn:

Be it known that I, DEWEY S. KnoHN, al

ycitizen of the United States, residing at Chicago, in the county of Cook and Stateof Illinois, have invented certain new and useful Improvements in Spindle-Body Bolts and MountingsTherefor, of which the following is a specication, reference being had to the accompanying drawings;

This invention relates to spindle body bolts and mountings therefor and more particularly to a spindle body Ibolt and mounting adapted for use for repairing and vrestoring worn spindle mountings.

An important object of the invention is to provide a device of this character which may be -readily applied to an aXle to replace the ordinary spindle bolt when the openings through which the spindle boltis ordinarily directed have become worn, so constructed that the ordinary spindle may be employed therewith. 1

As is wellknown to those familiar with the construction of a certain class of light motor vehicles, the front axle thereof.` is provided at its ends with forks affording vertically spaced arms Vthrough which Vis directed a bolt upon which the steering spindles and the front wheels are mounted." In the original mounting the bolt, is ldirected through the uppermost arm, andv threaded into the lowermost'arm. VIn use, due in some. instances to binding of the spindle body upon the bolt or to loosening of the securing elements of the bolt, the bolt rotates in its. mountings Vwith the result that the threadsy of this lower-arm become worn and finally will not hold the bolt against rotation. It will be obvious that the bolt, once free to rotate`,.wil1 wear the mounting openings of the arms to enlarge the same with the resulJ that a considerable throw of the front wheels the use of a device constructed in accordance.

with my invention the rethreading of the Figure '1.v

lower arm is eliminated and fufthermore` are use @fla boit, the body 'of which is of a diameter equal to the vbolt usually provided,

is permitted,` the advantage of this latter feature will immediately become obvious when it is pointed out that these spindle bodies are provided in their ends with bushings fitting the bolts and accordingly when a larger jboltl is employed it is -necessary Y either to ream these bushings to fit such bolt or to. provide an entirely` newbushing for the spindle body. Y

rPhe above and other objects I accomplish by the construction shown in the accompanying drawings, wherein for the purpose ofillustration is shown a preferred embodil ment vof my invention and wherein Figure 1 is a front elevation partially in section Vshowing repair parts constructed in accordance with my invention applied to an Y Figure 2 is a `bottom plan-view thereof;

and Y l Figure 3 is a section on the line 3 3 of Referring now more particularly to the drawings, the numeral 10 indicates a vehicle aXleyprovidedat its ,end with upper andlower spindle bolt arms11- and 121having vertically aligned-openings 13 and 14 formed therein. Inthe original construction of the axlethese openings 13 are of the same Size and the opening 14C of the lower arm 12 is Y screw-threaded for the reception ofthe lower end of the spindle body bolt.- These openings having become worn, for the reasons above 'set' forth, I provide a body bolt 15, the body portion 16 of which is of the same size as theqspindle bolt ordinarily employed. The.

upperl end ofthis body portion is enlarged, asindicated at 17,for a distance equal to the thickness of the upper arm 11, the upper end of this enlargement being provided with the `usual hexagon head 18. With the exceptionof the fact that this bolt'is of greater length than the original 'bolt employed and has th'eenlargeinent 17 formed thereon, the construction thereof is identical with that of the original bolt. Therexcess length of the bolt' isprovided so that ing 20 comprises a plate 21 abutting andv conforming to the shaping of the lower surface of the axle and the lower arm 12. The

the threaded vlower end 19 thereof will pro- Y V-.reception ofthe stud bolts 25 and having at its ii'pp'er end a'flange 28 adaptedto abut andf'clainpi'ngly engage over the*V opposite edge'of the aXlei-lange 2lvfroi'n'the flange 22 of the main plate 21.l rlhey openings 27 arel of' asizeV permitting aslight rocking movement 'of the'plate'Y 26 upon the "Studs and accerdingly .when the nuts 29 ofthe studs are tightened the plate 26V will take a bearing between the lower edge ofthe plate 21 and the edge ofthe flange 24 against,

which it bears,l thus enabling a lveryv rigid clampingrfof the plate 21 to the 4aXle. The side of the plate 21 bearing the flange 22 will disposed forwardly oiat'the forward side V'ofthe'ga'Xle and accordingly ,the securing elements vforfthis Qplatev and by means Yof which the' plateis Aclamped into position will be hidden from view andy the accessory will not materially affect the appearance of the vehicle. The outer endf'of ,the plate -21 is "provided with a threaded .opening 30 aligning with the Openigl and 14 and'with'which the ythreaded lower end of the bolt 15 engages. The `bolt 15 will extendfbeyoiid' the lower face ef this'plate i sufliciently to permit the eiig'ageiiient there# withof a castellat'ed' nut 31.

It will be seen 'from the foregoing that bythe use of a spindlezbody bolt Yandmountingitherefor constructed in accordance with y my invention, koldV and YwornV out ailles may lia'velth'e life thereof indefinitely Vextended and at the Isaine ytime standard spindle bod ies S- and spindle body bushings B may be employed.Y vIt "will, furtherinoreb b'e obvious that such a device may be very readily ap-V plied'to a vehicle, the onlyfoperatioii upon" enlarging the upper opening 13 to the diameterof the enlarged section 17 of theV bolt. Since many changes are possible in the'vconstruction'and arrangement of the mounting plate l do not limit myself to such specific structure thereof except as hereinafter. clamfied.`

l claim Y. 1. ,ln combination with an axle provided i at itseiid with vertically spaced spindle bolt` receiving arms having vertically aligned; openings formed therein, a spindle bolt mounted in saidy openings and fitting the opening of the yupper arm, and a plate seeiired tothe axle and extending beneath'the lower yarm Ahaving a threaded opening formed therein aligned with the openings ofl said spindle arms, the` lower end of Ysaid bolt being threaded and being engagediii the o ening of the plate. l j

2. n combination lwith an axle provided at its end with vertically spacedV spindle bolt receiving arms hai/*ing vertically aligned openings formed therein, a spindle` bolt mounted in said openings and Vhavin-g an enlargement fitting the opening pf the upper arm, 'and a plate secured to the axle andeXftending beneath the lower arm having a' threaded 'opening formed therein aligning with the openings of the 'spindle arms.- said plate being formed in .two's'eparable sections clampingly engaging the aXle,"the lower end ofthe boltbeing threaded and engaged throughtlie opening of the plate.

l3.7In combination with an vaide lprovided at its end with vertically spaced spindle bolt receiving arms having vertically Valigned openings formed therein, a spindle bolt mounted in said openings, and aI plate rigidly secured to the axle andY extending be- VSO neath the 'lower arm and conforming to the shape thereof, said4 plate having a threaded" Y opening formed therein aligned' with' the openings of the spindle arms, the lower enid ofthe bolt being' threaded and Jbeing k'enl gagedin the opening of the plate.
